The name is Potassium bromide.
Answer:
The answer is
<h2>7.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of rock = 14 g
volume = 2 cm³
The density of the rock is
We have the final answer as
<h3>7.0 g/cm³</h3>
Hope this helps you
Answer:
+2
Explanation:
Nickel (II) oxide, or NiO, is an ionic compound. Recalling a few rules of determining the oxidation number of substances:
1. Oxidation numbers of elements in ionic compounds are usually their own ionic charge
2. The total oxidation number of a neutral compound should be 0
And,
3. The oxidation number of oxygen in most cases is -2.
Therefore, since O in NiO has a oxidation number of -2, and nickel (II) ion usually has a charge of 2+, the oxidation number of Ni in NiO is +2 (always remember to put the positive sign in front of the number)
The solution for this problem is:
C6H5NH3Cl is a strong salt: C6H5NH3+ + Cl- C6H5NH3+ + H2O <-----> C6H5NH2 + H3O+
K = Kw/ Kb= 1.0 x 10^-14 / 3.8 x 10^-10= 2.6 x 10^-5
=2.6 x 10^-5 = x^2 / 0.240-x
x = [H3O+] = 0.00251 M
pH = 2.60 is the concentration
